Polymerizable composition based on epoxy acryl compounds with improved storage stability and method of preparing optical material based on the epoxy acryl compounds

摘要

The present invention relates to a polymerizable composition for an epoxy acrylic-based optical material and a method for manufacturing the epoxy acrylic-based optical material, in particular, a polymerizable composition and an optical for an epoxy acrylic-based optical material with improved storage stability that can prevent color changes during long-term storage at room temperature. It relates to a method of manufacturing a material. In the present invention, a polymerizable composition for an epoxy acrylic optical material comprising a compound represented by the following Chemical Formula 1, diphenyl dodecyl phosphite, and a phosphoric acid ester compound is provided. According to the present invention, the optical properties such as high refractive index and excellent Abbe's water, transparency, light weight, and heat resistance are excellent, and the manufacturing cost is low. A high quality epoxy acrylic optical material can be easily obtained, and the epoxy acrylic optical material of the present invention can be widely used in various fields by replacing the existing optical material.
